Why Time Seems to Speed Up as We Get Older

LIFE & DISCOVERY | CURIOFY LIFE

Remember when summer vacation seemed to last forever? Now a whole year can feel like it disappears between one holiday season and the next.

Many adults notice this strange sensation: time appears to pass faster as they grow older. But clocks have not changed speed. Our experience of time is shaped by attention, memory, emotion, and the way we look back on events.

Scientists are finding clues, though there is no single accepted explanation for why the years can feel shorter.

1. The Difference Between Living Through Time and Remembering It

There are at least two distinct questions. How fast does time feel right now? And how long does last month, last summer, or the last decade feel when you look back?

The answers can be very different. An afternoon in a waiting room may feel endless as it happens but leave hardly any memorable details. A vacation packed with unfamiliar experiences may pass quickly in the moment yet seem surprisingly long when remembered.

Researchers call this distinction prospective versus retrospective time judgment. Conflating the two can lead to overconfident explanations.

2. What the Research Actually Shows

In a 2005 study involving 499 people aged 14 to 94, psychologists Marc Wittmann and Sandra Lehnhoff found evidence supporting the common impression that time seems to accelerate with age—especially when people look back on longer periods.

But there is an important qualification: age explained only a modest share of the variation in responses, and the authors cautioned against strong causal claims. Not everyone experiences time this way.

More recent research published in 2026 explored whether people’s ability to form new memories was linked with how quickly the past decade seemed to pass. The findings pointed to memory encoding as a potentially important factor, but the research does not prove that adding more memories will literally slow time.

3. The Role of Novelty

Consider two weekends. During one, you follow an ordinary routine. During the other, you visit a new place, learn a skill, meet someone unexpected, and see something you’ve never seen before.

The novel weekend may create more distinct moments to remember. When you later look back, those memories can make the period feel richer and fuller.

This is one plausible explanation for why childhood can seem so spacious. Children encounter unfamiliar situations frequently, while adult routines may contain fewer standout moments. But novelty is only one possible contributor, not an experimentally established universal solution.

4. Why Attention Changes the Feeling of an Hour

When we are absorbed in an activity, we may pay less attention to the passing minutes. During boredom or anticipation, we often monitor time more closely.

Emotion can also alter time judgments: frightening or exciting moments may feel different from routine ones. These effects vary with the task, the person, and how researchers measure the experience.

The mind doesn’t contain a single stopwatch that works exactly like the clock on the wall. It relies on several processes that contribute to our sense of duration.

5. Can You Make Life Feel Fuller?

We cannot stop a year from passing. But we can deliberately create experiences that stand out in memory. You don’t need expensive travel or constant novelty to try.

Change one ordinary routine. Walk a new route, try a different recipe, or explore a local place you’ve never visited.
Learn something. A new language phrase, an instrument, or a practical skill creates opportunities for attention and memorable progress.
Notice the details. A conversation, a garden, or the evening sky may become richer when you give it undivided attention.
Make memories visible. A few photographs or short notes can help you remember distinct moments instead of allowing entire weeks to blur together.

These are ideas for living attentively, not proven treatments for changing the speed of subjective time.

6. A Different Way to Think About Growing Older

Perhaps the most important question is not, ‘How do I make time move slowly?’ It might be, ‘How do I make the time I have feel meaningful?’

A life measured only in calendar pages can seem to accelerate. A life filled with learning, connections, and noticing may feel different when we look back.

The Curiofy Life Perspective

The science of perceived time is still developing. Memory, attention, routine, and emotion all appear relevant, and the influence of age is more complicated than a catchy explanation would suggest.

The invitation is simple: keep discovering. Not because it can rewind the clock, but because a curious life offers more to remember.

Explore. Discover. Live Better.
